Replacement Piston Ring K267041211 for Zenoah G450PU (W/O PACKING)  [K267041211]

Replacement Ring for Zenoah G450PU Engines

Built to the manufacturer's designation, this piston ring fits G450PU engines and functions as the primary seal in the cylinder. Proper ring condition directly influences compression, blow-by control, and consistent throttle response on nitro remote control models.

Prior to assembly, check the piston and cylinder bore for scoring or wear, thoroughly clean mating surfaces, and confirm the ring seats uniformly. Installation varies by engine build, so protect the ring from nicks, position the gap according to the engine handbook, and apply a compatible lubricant during first starts and seating runs.

Swapping a worn ring is a routine maintenance action to restore peak compression and lower oil or smoke output. This item is supplied as a single spare for model engine rebuilds and servicing, offered without extra packing.
